The `/' would most likely have come from VMS or a precursor.  VMS has 
[had?] a remarkably well structured (too well structured?) CLI interface 
(I show my heritage :-).

Or `log/a FILE [COMMAND]'  or, hmm, something like:

	set log write FILE
	set log redirect FILE
	set log append FILE
	show log

and

	log[/a] FILE command-that-isn't-optional

Same for redirect.

Are you proposing that ``print/FMT'' gets replaced by ``print -FMT''. 
There shouldn't be two conflicting syntaxes.
